I have a fully restored Westfalia VW Bus parked inside our warehouse studio in Costa Mesa. We would call it semi-private in as much of a way that a bus is considered private. Many guests have likened it to camping.
The Observatory and Constellation Room are a popular nearby attraction. As well as SoCo, The Lab/Camp and Segerstrom Center for The Arts. Newport and Huntington Beach are all within 10 miles.
Parking is available on the street for free and public transportation by Bus is nearby. Taxis, Uber and Lyft are popular for getting around the area as well as most things are not far away.
